2. The data transmission system of claim 1 wherein the interleaver comprises a block interleaver configured to generate an interleaved data stream based on the data frames, the first-time varying stream being generated based on the interleaved data stream.
This invention relates to a data transmission system designed to improve signal integrity and error resilience in communication networks. The system addresses the problem of data corruption and signal degradation during transmission, particularly in environments with high interference or multipath effects. The core innovation involves an interleaver that rearranges data frames to mitigate burst errors and enhance error correction capabilities. The interleaver is specifically a block interleaver, which reorganizes data frames into a structured pattern before transmission. This process spreads out potential errors across multiple frames, making it easier for error correction mechanisms to reconstruct the original data. The interleaved data stream is then used to generate a first-time varying stream, which further enhances transmission robustness by dynamically adjusting signal properties to adapt to changing channel conditions. The system ensures that data is transmitted in a way that minimizes the impact of noise and interference, improving overall reliability and throughput. By using a block interleaver, the invention provides a structured approach to error mitigation, making it particularly useful in wireless, satellite, and other high-error-rate communication environments. The time-varying stream generation adds an additional layer of adaptability, allowing the system to respond to real-time channel variations.
